The steering wheel is attached to the steering rack by the steering shaft. When the steering wheel is turned, the steering rack interprets the directional input and pushes or pulls the front wheels in the desired direction. The steering rack is secured to the chassis.
To replace the steering rack, the steering shaft and steering tie rod ends must be removed (power steering lines must be removed if the vehicle is equipped with power steering). Hardware securing the steering rack to the chassis is removed, and the steering rack is removed from the vehicle. After the new steering rack is installed, the wheel alignment will need to be checked and adjustments made if necessary.
The steering rack boots must remain intact to prevent debris from entering the steering rack. This prevents premature wear of the steering rack and ensures steering precision.
The fluid level in a power steering system should not require topping up. If the fluid level requires topping up, this is a sign of a leak that needs to be investigated. If the power steering system is allowed to operate with a low fluid level, damage may occur.
